Below is an interactive U.S. map of State Highway Administrations (SHAs) that have developed either a draft, provisional, or standard specification on Balanced Mix Design (BMD). The map allows you to toggle between BMD approach, rutting test, and cracking test, for a quick view of which states are implementing the different practices. By clicking on the states you will be taken to that state’s summary of implementation efforts. This information was mainly collected from a survey of SHAs and the asphalt pavement industry conducted by the National Center for Asphalt Technology (NCAT) in May 2020. This information will be updated on a regular basis. If you see information that needs to be updated, please use the Contact Us link provided at the bottom of this page.
